+This is GDB, a source-level debugger intended for GNU,
+presently running under un*x.
+
+Before compiling GDB, you must set three files according to
+the kind of machine you are running on.
+
+param.h must be set up to #include an m- file for the machine.
+The m- files written so far are m-vax.h, m-sun2.h and m-sun3.h.
+(I believe that it is the operating system version and not
+the cpu type which determines which of the two is right on a Sun.)
+This file contains macro definitions that express information
+about the machine's registers, stack frame format and instructions.
+
+initialize.h must be set up to #include an m-...init.h file.
+There are two of them written: m-vaxinit.h and m-suninit.h.
+This file defines one macro, which says how to round up from the
+address of the end of the text of one .o file to the beginning of
+the text of the next .o file.
+
+pinsn.c must be set up to include the instruction printer for
+your cpu type.  The two printers that exist are vax-pinsn.c
+and m68k-pinsn.c.
+
+`Makefile' must be changed to say `OBSTACK = obstack.o' instead of
+`OBSTACK=-lobstack' (unless you want to install obstack.o as
+/lib/libobstack.a).
+
+Once these files are set up, just `make' will do everything,
+producing an executable `gdb' in this directory.
